ebeamtime is an open-source command-line tool that provides analytical estimation of electron-beam lithography write times based on GDSII layout files. It is designed for engineers and researchers in the field of electronic design automation (EDA) who need to predict and optimize lithography processes. The tool parses GDSII files and outputs estimated write times to aid in process planning.
ebeamtime sits in PulseGate's Other dev tools category. It focuses on estimating the write time required for electron-beam lithography from GDSII layout files. ebeamtime is an open-source project aimed at EDA engineers and researchers working with electron-beam lithography. The project is open source (GPL-3.0). ebeamtime is available on the command line.
It is developed by SandboChang, and the product first shipped in 2026. The project is developed in the open on GitHub with 13 commits in the last 90 days. Among its 5 catalogued features are GDSII parsing, write time estimation, and command-line interface.
